摘要： End reflectors, flat panel lens that may utilize the end reflector, and methods are provided. The end reflector for a flat panel lens may include a first grating having a first set of parallel planes. The first set of parallel planes may be of layers of alternating refractive indexes disposed at a first angle with a central plane of the flat panel lens. The end reflector may also include a second grating having a second set of parallel planes. The second set of parallel planes may be of layers of alternating refractive indexes of alternating refractive indexes disposed at a second angle with the central plane. The second angle may be equivalent to the first angle reflected about the central plane.

摘要： A light guide of the tapered-waveguide type includes an input slab (30) for expanding a projected image between an input end and an output end (40); and a tapered output slab (10) arranged to receive rays from the said output end of the input slab, and to emit them at a point on its face that corresponds to the angle at which the ray is received. The taper is calculated so that all rays injected into the input end undergo the same number of reflections before leaving the output face. The thickness of the input slab light guide (30) is greater in the transverse direction away from the centre line C, so that light travelling at the critical angle from the input face of the slab waveguide towards the output waveguide (10) bounces the same number of times in the input slab, regardless of its fan-out angle, in order to further reduce image distortion.

摘要： A light guide of the tapered-waveguide type includes an input slab (30) for expanding a projected image between an input end and an output end (40); and a tapered output slab (10) arranged to receive rays from the said output end of the input slab, and to emit them at a point on its face that corresponds to the angle at which the ray is received. The taper is calculated so that all rays injected into the input end undergo the same number of reflections before leaving the output face. The thickness of the input slab light guide (30) is greater in the transverse direction away from the centre line C, so that light travelling at the critical angle from the input face of the slab waveguide towards the output waveguide (10) bounces the same number of times in the input slab, regardless of its fan-out angle, in order to further reduce image distortion.

摘要： This document describes techniques and apparatuses for implementing an object-detecting backlight unit for a display device. An object-detecting backlight unit includes two or more light sources configured to provide light to a display to form an image, and a light sensor configured to receive reflected light when an object is near the display and determine that the reflected light originated from a region of the display. The reflected light is caused by light from the image reflecting off of the object back towards the display. The backlight unit is configured to detect a position of the object based on the region of the display from which the reflected light originated.
